Eight Posted May 18, 2011 Share Posted May 18, 2011 Quick question for you: I've just repaired some minor damage to an old combo with the intention of passing it on. The recipient may well be reading this and is probably going to get a bit worried. I've noticed that the earth wire from the mains plug isn't actually connected anywhere. It's just lolling around free as a bird. That doesn't seem right to me, but I'm not sure. I have actually played through the amp and didn't die - but should I go in and connect this to something?

Eight Posted May 18, 2011 Author Share Posted May 18, 2011 Just thinking about this some more... the inputs on the amp should be grounded to a metal part of the case, right? And shouldn't the earth wire from the mains socket also be connected to this metal? Quote Link to comment Share on other sites More sharing options...
icastle Posted May 18, 2011 Share Posted May 18, 2011 Yes. That green and yellow scrap of wire is potentially the only thing between you and disaster! Quote Link to comment Share on other sites More sharing options...

Eight Posted May 18, 2011 Author Share Posted May 18, 2011 (edited) I'm getting really paranoid about this now. To the point of testing all my other gear... Anyway, upon further investigation, it appears the earth wire was originally secured to the metal around the power transformer. Ran a few continuity checks and the ground side of the input jacks also goes there. I've reconnected the wire and all *seems* well. Plugging in a cable now shows that the ground bit of the jack is connected all the way through to the earth prong on the mains plug. Which is the same as on my Warwick Pro Fet. Noticed nothing different when I turned it on with a bass plugged in (and still not dead) but the whole thing has unnerved me.

Nothing to be nervous about, you've fixed one problem and tested the rest of your kit to ensure it's as it should be. Quote Link to comment Share on other sites More sharing options...
